>Description:
When running a kernel with "options MODULAR" it generates traps and panics as 
soon as it tries to load a module. This is due to various failings in 
sys/arch/arm/arm32/kobj_machdep.c:kobj_reloc().

In particular, the code for R_ARM_ABS32 fails to take addend in to account, and 
the code for R_ARM_PC24 fails to exist.

Some of the other code was a bit randomly structured (inconsistent coding 
styles).


>How-To-Repeat:
Build kernel and boot.
>Fix:
